WINDLASS FOR SETTING UP BARREL-BODIES.

SPECIFICATION forming part of Letters Patent N 0. 239,099, dated March 22, 1881.

Application filed May 8, 1880 To all whom it may concern:

Be it known that we, EDWARD HOLMES and BRITAIN HOLMES, citizens of the United lasses for Setting up Barrel-Bodies, fully delj'and end elevation.

scribed and represented in the following specifi eation and the accompanying drawings, forming a part of the same.

In said drawings, Figure 1 illustrates a frontside elevation of ourimproved machine, Fig. 2 being a plan or top view, and Fig. 3 a right- Fig. 4 is a rear elevation of the right-hand end of the machine. Fig. 5 is a sectional elevation of the worm-wheel and clutch, and Fig. 6 an inside face elevation of the pulleysupporting end post.

To form a barrel-bod y a num her of properlyshaped staves are assembled in circular form, by setting them up in a truss-hoop of suitable dimensions, in which such a number are placed vertically as will, with their edges resting snugly together, form a circular body tilling such hoop. Their lower ends being thus held, their upper ends flare outwardly to a considerable degree and require great power to bring them together so that their edges will meet and be adapted to receive a second truss-V hoop, which, with the first truss-hoop, secures the staves in the form of a barrel-body, which may be safely handled in the further manipulations necessary to finish it.

The present improvements relate to the machine known as a Windlass, which operates to draw the flaring stave ends together toreceive the second trussing-hoop.

The invention consists in a novel mechanism 1 controlling the movements of the Windlass which winds up the tightening-rope whereby its movements are regulated, and means for slacking said rope and unwindingit from said Windlass, also,in combinations of mechanisms, all particularly hereinafter set out and explained, and which will be more perfectly understood froin the followingdescription of a machine embodying the same.

The various mechanisms of the apparatus are supported by a heavy iron table, 25, that rests upon legs 26. At about the center of its front side this table is provided with a (No model.)

curved seat, 19, in which the flaring ends of the set-up staves of the partially-formed barrel-body may extend, so as to be in aconvenient position to have the loop of a tightening-rope, 18, placed over them. This tightening-rope, preferably made of wire, the loop of which is temporarily hung suspended from a hook, 27, on a rod, 28, rising vertically from the table, has one end securely secured by a link or links,

8, to the base of an end post, 29, and its opposite end fastened to the endof a drawing-chain, 22, that is attached to a winding-drum or windlass, 11, that is fast upon a transverse shaft, 9, which is mounted in brackets 10, that'rise from the face of the table at the end opposite to that carrying the post 29. This winding-drum or windlass-carryin g shaft is provided at one end with a worm-wheel, 20, that runs loosely upon it, which worm-wheel is rotated by means of a worm, 30, on a drivingshaft, 21, that is mounted in longitudinal bearings attached to the frame, and provided with a belt-pulley, 50, that runs loosely and nyay slide upon said shaft. The rotary motion of the pulley is transmitted to the driving-shaft by means of a friction wheel, 51, that is fast upon said shaft, and into frictional contact with the conical periphery of which the correspondingly-formed inner surface of the rim of said pulley isfoi'ced by means of a bellerank shifting-lever, 52, one end of which is joined by a connection-rod, 53, with the long arm of a lever, 54, that is pivoted to a lug, 13, projecting from the table, and

has its short arm forked to embrace a collar, 31, that tits in a flanged seat formed for it in itheelon gated hub 32 ofthe pulley. The normal position of these parts is thatshown in the drawings, and a movement of the lever 52 in the direction of the arrow will suffice to cause the shaft 21 to rotate. The rotary motion of the wor1n-wheel 20 is transmitted to the shaft 9 and the Windlass 11 by means of a clutchwheel, 12, that is splined upon the shaft 9, so as to slide thereon while rotating with said shaft, the teeth of which clutch -wheel 12 engage with the teeth of a similar wheel-projectin g from the rear face of the worm-wheel 20. The reciprocating movements of the clutchwheel12 are imparted to it by means ofa lever, 23, that is pivoted to 2.- lug, 14, projecting from the frame-work, the short arm of which lever is forked to embrace a collar, 6, that fits in a seat formed for it in the hub 7 of said clutchwheel v12. The long arm of the rod 23 is connected to one of the toggle-levers 15 16, the latter of which is fast to a longitudinal rockshaft, 24, the vibration of which is accomplished by means of a treadle, 33. The togglelever 15 is provided with a weight, 17, whereby said toggles are held extended, and thus vibrate the lever 23, so as to cause the clutchwheel12 to engage with the clutch of the wormwheel 20, and thus cause its rotating motion to be transmitted to the shaft 9 and to the windlass 11. When the lever 33 is depressed it throws the clutch-wheel12 rearward, and thus leaves the Windlass free to revolve in either direction.

As the free end of the chain 22 is secured to a slacking-chain, 34, that runs under a pulley, 4, and over a pulley, 5, that turn on bearings in the end post, 29, and is provided at its end with a weight, 35, it is apparent that after the chain 22 has been wound upon the Windlass 11, and thus raised the weight 35, that weight will descend, when the Windlass is free or unclutched, and unwind the chain 22.

Operation: The mechanisms being in the positions shown, and the flaring upper ends of the staves composing a partially-formed barrel-body having been placed within the seat 19, the attendant takes the looped tightening-rope 18 from the hook 24 and places it over the ends of the flaring staves. Then drawing the shifting-lever 52 toward the center of the machine forces the rotating pulley 50'into frictional contact with the frictional wheel 51, whereupon the shaft 21 is set in motion and rotates the worm 30, which, through the worm-wheel 20,-that is clutched to the shaft 9, sets the latter in motion and rotates the Windlass 11, which is thus turned by a movement of great power and winds up the chain 22, which, drawing upon the ti ghteningrope '18, shortens the bend of said rope around the stave ends, and thus draws them closely together. This done, the lever 52 is released, which allows the pulley to move outward, and thus suspend the movement of the worm 30, whereby the windlass ceases to turn. A truss-hoop is then placed over the staves to secure them in the position they have been drawn into. The treadle 33 is then depressed by the foot, and it acts, through the toggles and lever 23, to withdraw the clutch-wheel12 from engagement with the clutch of the wormwheel 20, thus leaving the Windlass free to turn withits shaft to unwind the chain 22 and release the tightening-rope from the barrel-body.

scent of the weight 35, that was raised by the winding up of the drawing-chain 22, which will thus pull the rope 18 rearward and give it the necessary slack to permit its being again placed over the greatly distended stave ends of another partially-formed barrel-body. 1n this condition it may be again hung upon the hook 27 as the treadle 33is released, and the barrel-body operated upon is released, and an incomplete one is brought to the machine.

Any other means for connecting the "driving-pulley with the shaft 21 to rotate the same may be employed. Said shaft 21 may be connected to the wheel 20, whereby the Windlassshaft is rotated, by miter-gearing, and the clutch mechanism connecting the shaft9 with the wheel 20 may be constructed in various ways.

What is claimed is- '1. The combination, with the Windlass 11 and the driving-wheel 20, rotatin gfreely upon the Windlass-shaft, of a clutch wheel, 12, mounted to slide upon and turn with the windlass-shaft, and provided with mechanism, substantially as described, that automatically maintains it in engagement with said drivingwheel, and is capable of being operated to disengage the same. I

2. The combination, with the Windlass 11 and the driving-wheel 20, rotating upon the Windlass-shaft, and aclutch-wheel, 12, mounted to slide on the Windlass-shaft and automatically maintained inengagement with said drivingwheel, of a weighted lever, 53, and its con nections, substantially as described.

3. The combination, with the tighteningrope, its drawing-chain, and windlass, of the weighted slacking-chain, substantially as described.

4. The combination of the shaft 21, provided EDWARD HOLMES. BRITAIN HOLMES.
